Abstract (en)

[origin: WO0031181A1] A wettable polypropylene composition comprising polypropylene and a hydrophilic, polar compound which includes functional sites selected from the group consisting of carboxyl, hydroxy, ether or ester moieties, wherein the polypropylene composition is wettable, having a contact angle less than or equal to 75 DEG . The hydrophilic polar compounds are selected from the group consisting of maleic anhydride-modified polypropylene (MAPP), acrylic acid modified polypropylene, ethylene acrylate modified polypropylene, polypropylene grafted with a sodium salt of an acrylic acid, polyethylene glycol (PEG), modified polyethylene glycol, polyvinyl alcohol (PVOH), polyvinyl formal (PVF); and monomer and dimer fatty acids having a carbon chain length in the range of 6 to 50, preferably 18 to 36. The compositions can further include the presence of an amorphous compound and surfactants.
